Answer:

The answer to your question is z = -3

Step-by-step explanation:

Expand                 42 = -7(z - 3)

                             42 = -7z + 21

Simplify                 7z = -42 + 21

                             7z = -21

Clear z                    z = \frac{-21}{7}

                              z = -3

bixtya [17]

Jummai and Tunde will each have 9 and 6 bananas respectively.

For the given ratio case we use the sharing ratio criterion to solve the problem.

Jummai is 12 years old.

Tunde is 8 years old.

Their ages are in ratio of;

                             A = 12 : 8

                             A =  3 : 2

The ratio's sum is 5.

15 bananas total are available for sharing.

Jummai will have x\\ bananas  x = (15 x 3/5) = 9

Tunde will have y bananas  y = (15 x 2/5) = 6

Jummai and Tunde will each have 9 and 6 bananas with them.

A television company charges $60 for the first half-hour of work and $40 for each additional hour. Blue mountain camp has budget
Alexandra [31]

Answer:

For a length of total of  4 hrs,  the budget of $200  will not exceed.

Step-by-step explanation:

Here, the first half hour charge for repairing = $60

The next hour charge  = $40 her hour

Total budget to be spent  by Blue Mountain Camp = $200

Now, here, the cost of 0.5 hour  = $60

So, the amount left after 0.5 hour repair  = $200 - $60 = $140

Let us assume we can hire the service for m hours in $140

Cost of 1 hour charge  = $40

Cost of m hour charge  = m X ( 1 hour charge) = m x ($40) = 40 m

⇒ 40 m = 140

or, m= 140/40 = 3.5, or m = 3.5

⇒ In $140 left, they can get a service of 3.5 hours at $40 per hour.

Now, the total hours of services hired = 0.5 hour in $60 + 3.5 hr in $140

= 0.5 hr + 3.5 hr = 4 hrs

Hence, for a length of total of  4 hrs, the budget of $200  will not exceed.
